DOOSAN PUMA MX1600ST CNC LATHE

Technical Description

The Fanuc 31i-B5 CNC control system is a high-performance, feature-rich controller designed for advanced turning and milling operations with enhanced 5-axis machining capabilities. It supports control of up to 20 axes and 6 spindles, enabling complex simultaneous machining processes. The control offers up to 5-axis simultaneous interpolation for precise contouring and complex shapes, supporting sophisticated tool path programming with nano-resolution interpolation for superior surface finish and accuracy. The system includes digital servo control with linear and exponential acceleration/deceleration profiles, feedrate overrides up to 254%, and adaptive feed functions to optimize machining cycles. Mechanically, this setup features an X-travel of 17.70 inches and a Z-travel of 36.80 inches, with a 35-inch distance between centers and a maximum swing over bed of 26.77 inches. The lathe can handle a maximum turning diameter of 13.00 inches and cutting length up to 34.50 inches. Bar capacity is 2.00 inches, with an 8-inch main chuck and a 6-inch secondary chuck on dual spindle spindles equipped with 20 HP motors running at 6,000 RPM. The spindle bore is 2.44 inches. Tool management includes 40 tool positions on the main turret and 16 on the secondary turret, providing extensive tooling flexibility. The machine also supports high-pressure coolant delivery at 1,000 PSI for efficient chip evacuation and thermal control. Overall, the Fanuc 31i-B5 CNC system combines advanced control algorithms, multi-axis simultaneous machining, and robust mechanical specifications to optimize precision, throughput, and machining complexity, ideal for modern production turning centers.
